Invalid Key Frame Type

[GamezMan]

I am trying to view certain models for the Thieves Den, and most of the assets for it can be viewed normally. A small handful though pop up an error when trying to open them. Weirdly enough some can be opened on earlier versions of GFD Studio (Only about 2 though from what I'm trying to view).

I don't know if this is an issue or not, but I thought I'd write it here just in case
